The mayor of a city in Massachusetts has promised to never drink Sam Adams beer after its founder praised President Trump for tax reform.

Somerville Mayor Joseph Curtatone tweeted that he will "never" drink the Boston-based brewery's product after founder Jim Koch thanked the president.

Koch was among a number of business executives who dined with Trump at the president's New Jersey golf course on Tuesday.

He said that Trump tax cuts were a "very big deal" for American brewers, "because 85 percent of the beer made in the United States is owned by foreign companies."

Curtatone also asked if Koch expressed "any concern" about Trump's immigration policies while thanking him for the tax break.

Massachusetts Senate candidate Geoff Diehl (R) said that Curtatone's boycott isn't a smart economic idea, given the amount of people working in Boston's beer industry.

"I think the smart money is on people drinking more Sam Adams," he said on "Fox & Friends." "Mayors getting involved in politics when it comes to beer... just a mistake."

He added that as a result of the president's tax bill, the Massachusetts State legislature is collecting more than $1.2 billion in unanticipated revenue.
